What are LED corn lights?

LED Corn Lights: A Comprehensive Guide (1)

Corn lights are designed as an energy-efficient replacement to high-intensity discharge (HID) lamps and SON lamps. They use a large arrangement of LEDs on their metal structure to provide a large amount of light. This arrangement of LEDs closely resembles a corn cob, hence the name “corn lights”.

They are used in places like car parks, football stadiums, street lights—anywhere that requires a lot of light. Unlike halogen HID lamps and SON lamps, LED corn lights can provide a large amount of light efficiently, while still retaining a wide colour spectrum.

If you are looking for a more efficient, cheaper replacement for a HID/SON lamp, corn lights could be the right product for you. Upgrading to LED means using up to 90% less energy. Great lighting that makes great savings. Click here to browse our full range and learn more.

Where are corn lights used?

Corn lights are an energy-rated replacement for any high-lumen lights, whether inside or out. They are used to light:

  • Car parks
  • Football stadiums
  • Streets
  • Roads
  • Interior high bay lamps
  • Housing and sporting complexes
  • Recreational areas (e.g. parks and fields)

Particulary useful in external applications due to their sturdy and splashproof build, LED Corn Lamps have become a go-to practical solutions for areas where unique bright lighting is needed.

* Metal halide: Produces light through a mixture of vaporized mercury and metal halides. Often used for sports stadiums, car parks, warehouses and other large spaces.

** Sodium Vapour Lamps: High-pressure sodium lamps that are often used in street lighting and general floodlighting.

*** Energy Ratings: All ratings for lighting products have since been re-evluated to make way for developing technologies. Why Have Our Energy Labels Changed?

Wattage Vs Lumens

A quick explanation of wattages and lumens.

Wattage: An amount of electrical power expressed in watts. In the past, we relied on watts (w) to show the brightness of a bulb. However, with the rise of energy-saving LED lighting, wattage simply doesn’t give us enough information. For example, a standard 40w CFL bulb will produce the same lumens as a 5w LED. Learn More: Which Light Bulb Wattage Do I Need?

Lumens: Used to measure the brightness of light. The higher the lumens (lm), the brighter the light. For an area that needs plenty of light, you will want to look at bulbs that offer a minimum of 5,000lm. The larger and darker the space, the more lumens it will require.

LED Corn Lamp Caps and Retrofitting

Retrofitting LED corn lamps can be a complicated procedure and it is recommended you hire a professional electrician. An electrician may ask you about your required corn light cap. The following is an explanation of the different corn light caps and the sockets they fit, giving you an understanding of what to look out for when purchasing or fitting corn lights. This information applies whether retrofitting, replacing, or just regular light fitting.

What Sockets Do Corn Lights Fit?

E27

Also known as the Edison screw. It is an extremely common light fitting and is used around the world. The E27 in particular is the most widely used amongst the Edison screw family, and is 27mm in diameter (hence the name).

E40

Also known as the Giant Edison Screw. The E40 lamp fitting was originally designed for lamps over 500W. However, thanks to the energy efficiency of LED bulbs, our LEDs can be as low as 20W while still retaining their brightness. The screw is 40mm in diameter.
